Abstract: | Many methods for the determination of pesticides residues in food have been reported. Although natural medicines should be confirmed as safe as food, only a few methods for the determination of pesticide residues in natural medicines have been reported. In this study, 10 pyrethroid pesticides were detected in natural medicines by GC/MS with negative chemical ionization (NCI). GC/MS with NCI can detect halogenated pesticides selectively, and thus is suitable for the detection of pyrethroid pesticides. This study indicates that GC/MS with NCI is useful for analyzing pyrethroid pesticides in natural medicines. |
